These buttons are made from Satsuma ceramics. They used to be exported in great quantities from southern Japan. There are many collectors of antique Satsuma in Europe and in the United States. Satsuma ware is a general name for pottery and porcelain, made in Satsuma and Osumi, in Shimazu clan (modern Kagoshima prefecture). In the Keian-era (1648-52), a technique of "brocade- pattern glazes," Nishikide Iro-e, was introduced from Kyoto, and Satsuma Nishikide (multi-colored Satsuma ware) began and was produced in a wide range of ceramics of colorful overglazed enamels. Distinctively, there are small cracks (called Kannyu) on the surfaces. These Satsuma buttons are still produced today, but they are quite rare. Our button collections are all new, not antiques.
